Sidcup Kent uk small circular object high in the sky visible for around 10 minutes moving north then right angle to east..we were laying on our hammocks, hot sunny clear day, we were looking at the guttering on our roof, when my husband noticed the object,he brought it to my attention, i have always been very sceptical about ufo etc..and said to husband it was a star, it was too slow to be a plane, too fast to be a weather balloon, and too slow for a satelite.The oject moved slowing in the north direction in a very staight line..we watched for a few minutes and then it suddenly changed direction not in a turning movement but an immediate right angle (east) we watched for around another minute..the object then increased speed and suddenly dissapeared out of sight.We are completely sober and drug free couple..this has really amazed us, hense getting sraight onto the net to report sighting
